#
#    $ docker build -t sodafoundation/delfin .
#
# 2. Export (optional) environment vars for hostnames for redis, rabbitmq and credentials for rabbitmq. Eg.
#    Here is example for exporting variable and its current values in setup.
#
#    $ export DELFIN_RABBITMQ_USER=delfinuser
#    $ export DELFIN_RABBITMQ_PASS=delfinpass
#    $ export DELFIN_RABBITMQ_HOSTNAME=rabbitmq
#    $ export DELFIN_REDIS_HOSTNAME=redis
#    $ export DELFIN_METRICS_DIR=/var/lib/delfin/metrics
#
# 3. Bring up delfin project using following command
#
#    $ docker-compose up -d
#
# 4. When finished using delfin project, bring down containers using following command
#
#    $ docker-compose down
#
# 5. To bring up delfin project with multiple service instances
#
#    $ docker-compose up -d --scale <<service-name>>=<<number of instances>>
#
#    example: Deploy delfin with 3 delfin-task and 2 delfin-alert instances
#       $ docker-compose up -d --scale delfin-task=3 --scale delfin-alert=2
#    Note: Multiple instances of delfin-api are not allowed
